Device and a method for operating an electronic utility device from a portable telecommunication apparatus

ABSTRACT

A server device has a programmable controller, a memory coupled to the controller, and a server program stored in the memory and executable by the controller. A first interface of the server device provides a first communication link to a portable telecommunication apparatus. A second interface connects the server device to an electronic utility device. The server program communicates with a client program in the portable telecommunication apparatus through the first interface. The server program also communicates with the electronic utility device through the second interface, so that digital information may be transferred between the portable telecommunication apparatus and the electronic utility device.

TECHNICAL FIELD

The present invention relates to the field of providing externalaccessibility to an electronic utility device and providing connectivityfor the electronic utility device to a global information network, suchas the Internet.

More specifically, the invention is directed at the use of a portabletelecommunication apparatus together with a separate server device foraccessing, controlling and operating an electronic utility device.

DESCRIPTION OF THE PRIOR ART

A portable telecommunication apparatus as set out above may for instancebe a mobile or cellular radio telephone for GSM (Global System forMobile Communication) or any other existing mobile telecommunicationssystem. Moreover, an electronic utility device according to the abovemay be an advanced accessory for the mobile telephone, for instance asatellite navigation module (GPS), an FM radio or a digital videocamera.

An electronic utility device according to the above may also be e.g. avideo recorder, a digital camera, a television set, a hifi stereo, or anair conditioner.

The various examples of electronic utility devices given above all havein common that they may normally be operated by a remote control unit,such as an infrared remote control unit, in addition to a local userinterface provided at a control panel of the device itself, such as aset of control buttons and LED indicators. Typically, a separate remotecontrol unit is used for each individual electronic utility device.

Although some infrared remote control units are programmable and maytherefore be adapted for use with several electronic utility devices,the existing approach has several drawbacks. First of all, remotecontrol units have a tendency of disappearing in many homes, especiallyin families where small children are present. Furthermore, the variousremote control units will have to be kept within reach of the intendeduser and will therefore occupy unnecessary storage space on desktops,table surfaces, etc. Moreover, the user interface of a typical remotecontrol unit has a low level of user friendliness; the user inter-faceis restricted to various small keys or buttons, at best in conjunctionwith a miniature LCD display. Finally, each type of remote control unithas its own philosophy behind the layout of the keys, etc, therebymaking it hard for users to get familiar with all different types ofremote control units.

Even if infrared remote control units are available for certainelectronic utility devices, they have no capabilities of providingconnectivity for the electronic utility device to a global informationnetwork, such as the Internet. Connectivity to e.g. the Internet isdesired e.g. for distributing information (such as pictures captured bya digital camera) or for performing error reporting and trouble shootingtogether with a web-based helpdesk run by a manufacturer or supplier ofthe electronic utility device in question.

Other electronic utility devices, such as printers, telefax machines,copying machines, or home appliances such as refrigerators or microwaveovens, are usually not operated from an infrared control unit. Instead,the user of these devices is restricted to a normally very limited localuser interface, such as a few control buttons and LED indicators,provided at a control panel of the device.

Consequently, there is a need for a well-defined, simple and inexpensiveway for a manufacturer of electronic utility devices to provide remoteaccessibility to the device. Correspondingly, there is a need for awell-defined, simple and inexpensive way for the utility devicemanufacturer to provide connectivity for the utility device to a globalinformation network, such as the Internet.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an easier way ofaccessing, controlling and operating electronic utility devices in astandardized and user-friendly fashion. A second object of the inventionis to drastically reduce the number of required remote control units,specifically so that only one control apparatus is required for a largenumber of electronic utility devices, which may exist in the environmentaround a user. A third object is to provide an opportunity of remotecontrol of electronic utility devices that traditionally are notprovided with such an option. A fourth object is to provide an optionfor various types of electronic utility devices to connect to a globalinformation network, such as the Internet, by using a single type ofcommunication device, namely a portable telecommunication apparatus.

The above objects have been achieved by the inventive understanding thatremote accessibility as well as connectivity to e.g. the Internet may beprovided for an electronic utility device through a portabletelecommunication apparatus by the use of an intermediate stand-aloneserver device, which communicates with a client program in the portabletelecommunication apparatus.

According to a preferred embodiment of the invention, a mobile WAP(Wireless Application Protocol) telephone having a built-in WAP browseris designed to connect via a point-to-point communication link to astand-alone WAP server module or device through an accessoriesinterface, such as a short-range radio link, an infrared link or aserial cable link. The WAP server module is provided with an embeddedWAP server and an interface for connecting to an electronic utilitydevice. The electronic utility device stores information related to thedevice functionality in the form of WML (Wireless Markup Language) pagesand WML scripts. This information may be transferred to the WAP serverof the WAP server module, which in turn may forward the information tothe WAP client of the portable telecommunication apparatus to bepresented to a user. Control information may be entered by the userthrough the WAP client and transferred to the WAP server and,ultimately, the electronic utility device, so that the functionalitythereof may be remotely controlled from the portable telecommunicationapparatus.

A solution to the above objects is defined by the appended independentpatent claims. Other features, advantages and objects of the inventionwill appear from the following detailed disclosure of a preferredembodiment, from the appended drawings as well as from the subclaims.

DETAILED DISCLOSURE OF A PREFERRED EMBODIMENT

FIG. 1 is intended to illustrate the general inventive concept accordingto the present invention, i.e. that a user of a mobile telephone 1 oranother type of portable telecommunication apparatus will be able toaccess, control and operate a plurality of telephone accessories, homeappliances or other external electronic utility devices 30, 40, 50through a WAP browser built into the mobile telephone. To this end, eachelectronic utility device 30, 40, 50 is connected (as indicated byreference numeral 33) to a respective WAP server module 31, 41, 51, fromwhich the WAP browser of the mobile telephone 1 will receive encoded WMLpages. The pages transmitted from the WAP server module 31, 41, 51 tothe mobile telephone 1 represent the services, functionalities andapplications, which are offered by the respective electronic utilitydevice 30, 40, 50. As will be described in more detail below, theinformation contents of the WML pages may change dynamically, andmoreover the user may feed back information to the respective utilitydevice 30, 40, 50 by e.g. filling in WML forms and pushing theinformation back to the WAP server module 31, 41, 51 and the utilitydevice 30, 40, 50. In this way, the user of the mobile telephone 1 mayoperate the respective utility device 30, 40, 50 and control thefunctionality thereof.

As shown in FIG. 1, the mobile telephone 1 comprises an antenna 10,which in a conventional way is used for connecting the mobile telephone1 to a mobile telecommunications network 21 through a radio link 23. Ina well-known way, the mobile telecommunications network 21, for instanceGSM, offers voice, data and fax call services to the user of the mobiletelephone 1. By means of the antenna 10, the user of the mobiletelephone 1 may also access the Internet 20, or another globalinformation network, by using the built-in WAP browser of the mobiletelephone 1. To this end, graphic information and/or text is presentedon a display 13, and a set of cursor navigation keys 14 a are providedin a keypad together with a set of ordinary mobile telephone keys 14 b.The latter comprise e.g. a YES/OK/ANSWER key, a NO/CANCEL/HANG UP key,numeric keys 0-9 as well as other character keys, such as * and #.

As is well known, the mobile telephone 1 also comprises a loudspeaker 11and a microphone 12. Moreover, the mobile telephone 1 of the preferredembodiment shown in FIG. 1 comprises an infrared interface 15, such asan IrDA port, by means of which the mobile telephone 1 may be connectedvia a first WAP server module 41 to a first electronic utility device inthe form of a television set 40 in FIG. 1.

The mobile telephone 1 also comprises a system or accessories connector16, by means of which the mobile telephone 1 may be connected, through aserial cable 52 (e.g. RS232) and a second WAP server module 51, to asecond electronic utility device in the form of a digital camera 50 ofFIG. 1.

The mobile telephone 1 additionally comprises a second antenna 17 forestablishing a short-range radio link 32, such as a Bluetooth link, to athird electronic utility device in the form of a vending machine in FIG.1, via a third WAP server module 31.

An essential portion 200 of the mobile telephone 1 is shown in FIG. 2. Acontroller or CPU 210 is coupled to a random access memory 220 and todrivers 250 for the user interface formed by the display 13 and thekeypad 14 a-b. The controller 210 is also connected to a permanentmemory 230 in the form of a flash memory. The flash memory 230 comprisesan operating system 232 as well as an information access program in theform of a WAP client 240, which will be described in more detail below.The mobile telephone also comprises physical interfaces 260, 262 and 264for the external device interfaces 15, 16 and 17 in FIG. 1. In moredetail, interface 260 is an RS232 module for the system or accessoriesconnector 16, interface 262 is an IrDA module, and interface 264 is aBluetooth module.

As shown in FIG. 2, the WAP client 240 comprises a stack of protocols241-246 as well as a datapath selector 248, the purpose of which will bedescribed later. On a first level or top level 241 a WAP browserapplication is provided, which when executed by the controller 210 willform a graphical user interface on the display 13 and allow the user toaccess the respective WAP server modules 31, 41, 51 of the availableelectronic utility devices 30, 40, 50. A second level 242 is a wirelesssession protocol. As a third and fourth level, respectively, a wirelesstransport protocol and a wireless datagram protocol are provided,respectively. The protocols 241-244 are all essentially known per se andare not described in more detail herein.

On a fifth level 245 a respective adaption layer is provided for theserial cable interface 16, 260, the infrared interface 15, 262 and theBluetooth interface 17, 264. The physical layer of the respectiveinterface is provided as a sixth protocol level 246. The adaption layer245 thus adapts the overlying wireless datagram protocol 244 to threedifferent bearers, i.e. cable, infrared and Bluetooth.

Moreover, a GSM layer 245, 246 is also provided, as is generally knownin the field of mobile WAP telephones, for providing the firstcommunication link 22 between the antenna 10 and the Internet 20 (FIG.1).

The purpose of the datapath selector 248 is to direct WML requests fromthe WAP browser 241 to either the first communication link 22 (through acircuit-switched GSM data call connection or through SMS-Short MessagesServices), or to the respective external device interface 16, 52, 260(cable), 15, 42, 262 (infrared) and 17, 32, 164 (Bluetooth). In thepreferred embodiment, this differentiation is achieved through a newaddress scheme for the Uniform Resource Identifier (URI)/UniformResource Locator (URL). For instance, when access is to be made acrossthe first communication link 22 to ordinary web sites on the Internet20, the ordinary URI/URL format “http:// . . . ” may be used.Conversely, when any of the electronic utility devices 30, 40, 50 is tobe accessed, the URI/URL may look like: “local:// . . . ”.

FIG. 3 is a schematic illustration of an essential portion 300 of any ofthe stand-alone WAP server modules 31, 41, 51 shown in FIG. 1. Acontroller or CPU 310 is connected to a random access memory 320 and anon-volatile memory 330, which is a flash memory in the preferredembodiment. The flash memory comprises an embedded WAP server 340, whichwill be described in more detail below.

The WAP server module 300 further comprises a utility device interface350, which will be used for operatively coupling the WAP server moduleto its electronic utility device. Consequently, the vending machine 30in FIG. 1 will be physically connected to its WAP server module 31through a serial cable 33, the utility device interface 350 of the WAPserver module 31 and a corresponding physical interface in the vendingmachine 30. Even if a serial cable 33 is used according to the preferredembodiment, the WAP server module may be connected to its electronicutility device by another communication link than a serial cable.

Referring back to FIG. 3, the WAP server module 300 finally comprisesphysical interfaces for connecting to the mobile telephone 1 in the formof a cable interface 360 (link 52 in FIG. 1), an infrared interface 362(link 42 in FIG. 1) and a Bluetooth interface 364 (link 32 in FIG. 1).

The WAP server 340 comprises a stack of protocols 341-346, whichcorrespond to the stack of protocols 241-246 in the mobile telephone 200shown in FIG. 2. At the top level a WAP server application protocol 341is provided. Then follows a wireless session protocol 342, a wirelesstransport protocol 343, a wireless datagram protocol 344, an adaptionlayer 345 for different physical interfaces (cable, infrared orBluetooth) and, finally, a physical interface layer 346. Preferably, theprotocol stack of the WAP server 340 is adapted to all possible bearers,even if only one physical bearer 360 is used (such as either cable,infrared or Bluetooth). This makes it easier to design a genericstand-alone WAP server module 300.

The WAP server 340 further comprises an external file and functionprotocol 348 which is used for communicating with the electronic utilitydevice 30, 40, 50 (illustrated in more detail in FIG. 4) through theutility device interface 350 and the physical link 33.

FIG. 4 is a schematic illustration of an essential portion 400 of any ofthe electronic utility devices shown in FIG. 1, i.e. the vending machine30, the television set 40 or the digital camera 50. A controller or CPU410 is connected to a random access memory 420 and a driver 450 for alocal user interface. The local user interface may for instance bebuttons for capturing, deleting or scrolling through pictures and aminiature LCD display on the digital video camera 50, program selectionbuttons, volume controls, brightness controls, etc, on the televisionset 40, or buttons for choosing among e.g. coffee, tea, cappuccino orespresso on the vending machine 30.

The controller 410 is coupled to a non-volatile memory 430, which is aflash memory in the preferred embodiment. The flash memory 430 comprisesdigital information (WAP contents 440), which constitute the contentsthat will be supplied by the WAP server module 300 to the mobiletelephone 1, 200.

The electronic utility device 400 also comprises a WAP server moduleinterface 460 for connecting the electronic utility device 400 to theWAP server module 300 through e.g. a serial cable.

The WAP contents 440 comprise a virtual file system 432, which has thepurpose of storing a plurality of WML pages 438 and a plurality of WMLscripts 439 in a structured and readable way. The WAP contents 440 alsocomprise Server Side Include (SSI) functions 436, which enable a programdeveloper to insert directives inside the WML code to instruct the WAPserver module 340 to replace the directive with a dynamic content uponretrieval of the WML code.

The WAP contents 440 also comprise Common Gateway Interface (CGI)functions 434 for enabling user input from the WAP client of the mobiletelephone 1 to the WAP server module 340 and the utility device 400. TheCommon Gateway Interface functions 434 are a set of CGI routines that,when executed by the controller 410, controls a respective aspect orparameter of the functionality provided by the electronic utility device400. For instance, if the utility device 400 is a digital camera 50,different CGI routines are provided for controlling e.g. the pictureresolution, for scrolling through pictures stored in the camera, forcapturing a new picture, for setting date/time, etc.

The WML pages 438 and the WML scripts 439 are preferably stored aspre-compiled binary WML files. Alternatively, the contents may be storedas non-binary WML files, which are encoded into binary WML files by theWAP server 340 upon request from the WAP client 240 of the mobiletelephone 1.

As appears from the above, the total WAP server functionality is dividedinto two separate parts; the stand-alone WAP server module 300 and theWAP contents 440 of the electronic utility device 400. This has severaladvantages. Firstly, all functionality data and operational parametersrelated to the particular electronic utility device 400 (digital camera,vending machine, etc) is defined by the device manufacturer and storedin the utility device itself. Therefore, the WAP server module 300 doesnot require any specific knowledge about the particulars of anindividual electronic utility device, and thus the WAP server module 300may be used with any electronic utility device, that fulfills thespecification above. Moreover, the manufacturer of the device 400 doesnot have to bother about how the actual connection is established to theportable telecommunication apparatus; this will fully be taken care ofby the intermediate WAP server module 300.

The communication between the electronic utility device 400 and the WAPserver module 300 is handled by the external file and function protocol348 and 448, which is implemented in both the WAP server module 300 andthe electronic utility device 400 and allows exchange of WML pages, WMLscripts as well as execution of CGI and SSI functions. The external fileand function protocol 348, 448 contains a set of commands for performingthe above, such as commands for initializing e.g. the serial link 33(baudrate, etc); commands for seeking for a WML page/script or CGI/SSIfunction in the memory 430 of the electronic utility device 400;commands for opening and closing such a file; commands for reading fromand writing to such a file; and commands for invoking CGI and SSIfunctions in the memory 430 of the electronic utility device 400. Theexternal file and function protocol 348, 448 also comprises errorhandling.

The rest of this specification will deal with the use of the mobiletelephone 1/200 of FIG. 2 for controlling the electronic utility device440 of FIG. 4 through the WAP server module 300 of FIG. 3. Obviously,the user must be able to easily access at least his/her favoriteelectronic utility devices 30, 40, 50 from the mobile telephone 1.Preferably, a dynamic menu system is implemented in the mobile telephone1, which allows the addition of a short cut menu option for connectingto a respective utility device 30, 40, 50 through a corresponding WAPserver module 31, 41, 51. Preferably, the WAP server modules 31, 41, 51are designed to transmit an initial sequence of identifying commands tothe WAP client 240 of the mobile telephone 1/200, when the mobiletelephone and the WAP server module are interconnected.

Thus, useful information such as physical bearer type (cable, infraredor Bluetooth), possibly an address identifier (particularly in the caseof Bluetooth) as well as the name of a WML start page are submitted bythe WAP server 340 to the WAP client 240 upon interconnection of themobile telephone 1/200 and the WAP server module 300. These parametersare stored together with the respective shortcut in the dynamic menusystem of the mobile telephone 1/200. Alternatively, some of theparameters above, particularly the name of the start page, may bestandardized, e.g. “index.wml”. Still another alternative, at least forsome physical bearers, particularly Bluetooth, is that the name of thestart page is retrieved through service discovery.

Three use cases involving the mobile telephone 1 and the digital camera50 will now be described. It is assumed that the digital camera 50 iscapable of producing digital pictures and storing them locally in e.g.the flash memory 430. As described above, the digital camera 50 may beconnected through a serial cable to the WAP server module 51, which inturn is connected through a serial cable 52 to the accessories interface16 of the mobile telephone 1. Obviously, the camera could equally wellhave been connected via an infrared or Bluetooth interface. The WAPserver module 51 is provided with the WAP server 340 shown in FIG. 3,and the digital camera 50 is provided with the WAP contents 440 shown inFIG. 4.

Initially, the user takes a few pictures using the digital camera 50.The user then connects his/her mobile telephone 1 to the WAP servermodule by means of the serial cable 52. A WML start page is then fetchedby the WAP server 340 from the camera 50 and forwarded to the WAP client240 across the serial cable 52, and the start page is presented on thedisplay 13. The start page contains a plurality of controls,representing different functions of the digital camera 50. The user mayfor instance choose to view the pictures captured in the digital camera50. The pictures are then sent, one by one, from the camera 50 via theWAP server 340 of the WAP server module 51/300 to the WAP client 240,which presents the pictures on the display 13 of the telephone 1.

The user may then select one of the pictures, that he/she wants topublish on the Internet 20. The user may specify a certain WAP or webserver available on the Internet by filling in its HTTP (HypertextTransfer Protocol) address in a WML form submitted from the WAP server340. A dial-up GSM data connection 22 (FIG. 1) is established with anInternet service provider, and the WAP browser 240 of the mobiletelephone 1 connects to the specified WAP or web server on the Internet.The selected picture is then sent over the link 22 for publication onthe specified WAP or web server. Finally, the user disconnects themobile telephone 1 from the WAP server module 51, wherein the logicalconnection between the WAP browser 240 and the WAP server 340 will beinterrupted too, as well as the dial-up connection 22 to the Internet.

In the second use case, the user connects his telephone to the digitalcamera via the WAP server module, as described above. The start pagefrom the digital camera is presented on the display of the telephone.The user then enters a maintenance menu provided by the digital camera.All available settings for the digital camera are presented on a WMLpage submitted by the WAP server 340. These settings may for instanceinclude the following functionality: capture picture, delete picture,scroll through pictures, resolution setting, color setting, flash mode,date/time settings, etc. The user may then select any setting and changeits value. The changed value will be pushed back from the WAP client 240to the WAP server 340 according to the methods described above, whereinthe WAP server 340 will recognize the changed value and invoke a CGI orSSI routine in the camera 50 for changing the setting of the digitalcamera 50. When the user is finished, he/she will disconnect the mobiletelephone 1 from the WAP server module 51, as described above.

In a third use case it is assumed that the digital camera has amalfunction. The user notices this and connects the camera 50 to themobile telephone 1, as described above. The WAP server 340 executes apredetermined error diagnosis WML page 438 stored in the camera 50,which in turns invokes a CGI routine of the CGI module 434. The CGIroutine fetches an error code from the controller 410, and this errorcode is submitted together with a predetermined HTTP address by the WAPserver 340 to the WAP client 240 of the mobile telephone 1. A dial-upGSM data connection 22 (FIG. 1) is established with an Internet serviceprovider, as described above. The WAP browser 240 of the mobiletelephone 1 connects to the predetermined HTTP address, which points ata help-desk web site provided by the manufacturer or supplier of thedigital camera 50. The error code is then transferred to the help-deskweb site, which will return a clear-text message, illustrative image,etc., which explains the nature of the error and how it is best dealtwith by the user.

A fourth use case involves the vending machine 30 of FIG. 1, which isexemplified as a machine, where a user may purchase hot drinks, such ascoffee, tea, cappucino, espresso, etc. The user may buy a hot drink andpay for it by using his/her mobile telephone 1. As described above, theuser connects the mobile telephone 1 to the WAP server module 31 of thevending machine 30 by e.g. invoking a short cut menu option in themobile telephone 1. A WML start page will be fetched by the WAP servermodule 31 through the link 33 from the memory 430 of the vending machine30, and this start page will be transmitted across the Bluetooth link 32to the mobile telephone 1, where the WML start page will be presented bythe WAP browser 240. The start page may for instance present a welcomemessage, a logotype, etc.

In a subsequent WML page, the user may be presented to a form, wherehe/she may choose what type of hot drink to purchase. In a third WMLpage, the price of the purchase may be presented on the display 13,together with a question whether the user wants to complete thepurchase. The user accepts the purchase, and an electronic wallet in themobile telephone may be charged.

The present invention has been described above with reference to apreferred embodiment. However, other embodiments than the one describedabove are equally possible within the scope of the invention, as definedby the appended independent claims, which is readily realized by a manskilled in the art. Specifically, other physical bearers than cable,infrared and short-range radio link are possible within the scope of theinvention. Also, the invention is applicable to other electronic utilitydevices than the ones exemplified above, including but not limited tovideo recorders, hifi stereos, air conditioners, refrigerators ormicrowave ovens.

The server module 300 may be connected to the electronic utility device400 in other ways than the one described above (serial cable), forinstance by a wireless link, an optical link, or by direct galvaniccoupling (particularly if the server module 300 is realized as anintegrated circuit, which may soldered onto a printed circuit board ofthe electronic utility device 400).

Moreover, the WAP client of the mobile telephone may be substituted foranother information access program for accessing a global informationnetwork, possibly different than Internet. Correspondingly, the WAPserver of the electronic utility devices may be substituted for anotherkind of information provider server.
